Abstract
In this study, the photothermal effect of magnetic nanoparticle clusters was firstly reported for the photothermal ablation of tumors both in vitro in cellular systems but also in vivo study. Compared with individual magnetic Fe3O4 nanoparticles (NPs), clustered Fe3O4 NPs can result in a significant increase in the near-infrared (NIR) absorption. Upon NIR irradiation at 808 nm, clustered Fe3O4 NPs inducing higher temperature were more cytotoxic against A549 cells than individual Fe3O4 NPs. We then performed in vivo photothermal therapy (PTT) studies and observed a promising tumor treatment. Compared with PBS and individual magnetic Fe3O4 NPs by NIR irradiation, the clustered Fe3O4 NPs treatment showed a higher therapeutic efficacy. The treatment effects of clustered Fe3O4 NPs with different time of NIR illumination were also evaluated. The result indicated that a sustained high temperature generated by NIR laser with long irradiation time was more effective in killing tumor cells. Furthermore, histological analysis of H&E staining and TUNEL immunohistological assay were further employed for antitumor efficacy assessment of PTT against A549 tumors.

Abstract
Nanoparticles have shown great potential in biological and biomedical applications due to their distinct physical and chemical properties. In the meanwhile, the biosafety of nanoparticles has also raised intense concerns worldwide. To address such concerns, great efforts have been made to examine short-term effects of nanoparticles on cell survival and proliferation. More recently, exploration of long-term effects of nanomaterials, particularly those with promising biomedical applications in vivo, has aroused significant interest. For example, gold nanoparticles (AuNPs) are generally considered non-toxic to cell growth, whereas recent studies suggest that AuNPs might have long-term effects on cellular metabolism and energy homeostasis. In this Review, recent advances in this direction are summarized. Further, possible mechanisms under which nanoparticles regulate metabolic signaling pathways, potential long-term effects on cellular anabolic or catabolic processes, and their implications in human health and metabolic disorders are discussed.

Abstract
Over the last decade, significant progress has been made in the field of drug delivery. The advent of engineered nanoparticles has allowed us to circumvent the initial limitations to drug delivery such as pharmacokinetics and solubility. However, in spite of significant advances to tumor targeting, an effective treatment strategy for malignant tumors still remains elusive. Tumors possess distinct physiological features which allow them to resist traditional treatment approaches. This combined with the complexity of the biological system presents significant hurdles to the site-specific delivery of therapeutic drugs. One of the key features of engineered nanoparticles is that these can be tailored to execute specific functions. With this review, we hope to provide the reader with a clear understanding and knowledge of biological barriers and the methods to exploit these characteristics to design multifunctional nanocarriers, effect useful dosing regimens and subsequently improve therapeutic outcomes in the clinic.

Abstract
The abundant extracellular matrix (ECM) in the glioma microenvironment play a critical role in the maintenance of glioma morphology, glioma cells differentiation and proliferation, but little has been done to understand the feasibility of ECM as the therapeutic target for glioma therapy. In this study, a drug delivery system targeting fibronectins (FNs), a prevailing component in the ECM of many solid tumors, was constructed for glioma therapy based on the interaction between the abundant FNs in glioma tissues and the FNs-targeting moiety CLT1 peptide. CLT1 peptide was successfully conjugated to PEG-PLA nanoparticles (CNP). FNs were demonstrated to be highly expressed in the ECM of glioma spheroids in vitro and glioma tissues in vivo. CLT1 modification favored targeting nanoparticles penetration into the core of glioma spheroids and consequently induced more severe inhibitive effects on glioma spheroids growth than traditional NP. In vivo imaging, ex vivo imaging and glioma tissue slides showed that CNP enhanced nanoparticles retention in glioma site, distributed more extensively and more deeply into glioma tissues than that of conventional NP, and mainly located in glioma cells rather than in extracellular matrix as conventional NP. Pharmacodynamics outcomes revealed that the median survival time of glioma-bearing mice models treated with paclitaxel-loaded CNP (CNP-PTX) was significantly prolonged when compared with that of any other group. TUNEL assay demonstrated that more extensive cell apoptosis was induced by CNP-PTX treatment compared with other treatments. Altogether, these promising results indicated that this ECM-targeting drug delivery system enhanced retention and glioma cell uptake of nanoparticles and might have a great potential for glioma therapy in clinical applications.
